APG series

Edwards APG100 series Active Pirani vacuum gaugesare available in 2 models. The
APG100-XM is the standard model and measures to 10-3 mbar. The APG100-XLC is a
corrosion resistant version with measurement to 10-4 mbar.

Both Edwards APG100 gauges feature compact size for easy installation, a linear output, and a replaceable
sensor tube. The new gauges are compatible with all Edwards Vacuum TIC instrument
controllers and other active gauge controllers and displays. They are also CSA, C/US
approved as well as fully RoHS compliant due to their lead-free construction

Features and Benefits;

Cable connections and gauge adjustment conveniently located, thereby minimizing the space envelope required for access
Sensor tube can be baked to 150 ºC
Adjustable set-point for simple process control and interlocking
Remote calibration possible
Linear output – 1 volt per decade for easy interface with vacuum control systems
NW16 and NW25 flange options for easy connection to vacuum systems – other flange options on request
LED status indicator shows normal and fault conditions

The Edwards APG, is a Pirani vacuum gauge and gauge controller in a single compact unit. The measurement range of the APG-M and of the corrosion-resistant APG-MP is 100 to 1 x 10-3 mbar: the range of the APG-L is 10 to 1 x 10-4 mbar. All of the gauges will indicate pressures up to 1000 mbar at reduced accuracy. The APG requires a 20 to 36 V d.c. power supply: it has a 2 to 10 V d.c. analogue output which is related to pressure. The APG is compatible with all of the Edwards AGC’s (Active Gauge Controllers) and with the appropriate versions of the Edwards AGD’s (Active Gauge Displays). Alternatively, you can use an independent power supply for the APG and you can read the APG output signal with a voltmeter or an analogue- to-digital converter.

An 8-way electrical connector socket on the APG is used to connect the APG to your AGC, AGD or electrical supply and voltmeter. Electrical cables fitted with suitable connector plugs are available as accessories. A gauge identification signal is available on the electrical connector: this signal is used by Edwards AGC’s to identify which type of Active gauge is connected, that is one of the following types:

Edwards APGX-H-NW16 (Stainless Steel) Linear Convection Vacuum Gauge has a wide measuring range from 1333 to 3 x 10-4 mbar (1000 to 2.3 x 10-4 Torr). The use of APGX-H-NW16 convection technology ensures accuracy and sensitivity are maintained to the top of the range.

The Edwards APGX-H-NW16 is compact and may be mounted in any orientation, simplifying installation where space is limited. The gauge incorporates a setpoint and two LEDs, which indicate setpoint and gauge status.

The Edwards APGX-H-NW25 uses the constant temperature principle in which the cooling effect of the gas on the filament is overcome by varying the voltage applied, which in turn maintains a constant resistance and keeps the circuit in equilibrium. This voltage is therefore a measure of the pressure in the gauge tube. It should be noted that different gasses have different thermal properties and as such the output of Edwards APGX-H-NW16 is gas dependant.
